COMPASSES.

SPECIFICATION forming part of Letters Patent No. 768,333, dated August.23, 1904.

Application filed July 11, 1904.

T0 00% whom it may concern:

Be it known that I, GEORGE LE BLANo, a citizen of the United States,residing" at Beecher Falls, in the county of Essex and State of Vermont,have invented a new and useful Compass, of which the following is aspecification. This invention relates to dividers or compasses employedby carpenters and other mechanics, and has for its object to provide asimply-constructed and convenient implement which may be quicklyadjusted to any desired degree and firmly locked in position.

Another object of the invention is to provide a simply-constructed andconvenientlyarranged pencil or scriber holder for attachment to one ofthe legs of the implement.

With these and other objectsin view, which will appear as the nature ofthe invention is better understood, the same consists in certain novelfeatures of construction, as hereinafter fully described and claimed.

In the accompanying-drawings, forming a part of this specification, andin which corresponding parts are denoted by like designating characters,is illustrated the preferred form of the embodiment of the inventioncapable of carrying the same into practical operation, it beingunderstood that the invention is not necessarily limited thereto, asvarious changes in the shape, proportions, and general assemblage of theparts may be resorted to without departing from the principle of theinvention or sacrificing any of its advantages.

In the drawingsthus employed, Figure 1 is a perspective view of theimprovedimplement in one of its positions. Fig. 2 is a side view of theupper portion of the same, showing the implement in another of itspositions. Fig. 3

represents the parts forming the pencil or scriber holding attachmentdisconnected.

The improved implement comprises two leg members 1O 11, pointed at oneend, as at 12 13, and with the other ends bent in opposite directions,as at 14 15. Pivoted by its ends at 16 17 to the members 11 at-theelbows of the bends is a head member 18, and mounted for movementcentrally through this head member is a rod 19, the head member having aset-screw 20 for holding the rod at any desiredpoint in the head member.Connecting Serial No. 216.093. (IlomodeL) one end of the rod 19respectively to the bent ,portions 14 15 of the leg members are links 2122, being pivoted, as at 23 24, to the leg members and at 2526 to therod, as shown. By this simple means it will be obvious that the pointedends of the leg members may be distended to any desired extent withinthe range of the links 14 15 and the length of the rod 19 and clamp themfirmly in any desired position by means of the set-screw 20.

When a relatively short distention of the leg members is required, therod 19 will be adjusted inwardly or toward the pointed ends 12 13, as inFig. 1; but when a greater range is desired the rod willbe adjustedoutwardly, 5 as in Fig. 2, which will permit the pointed ends of thelegs to berdistended to a much greater extent, as will be obvious. Thusthe implement can be very readily adapted to the work required of it. Apencil or scriber supporting attachment is provided consisting of twoclamp-plates 27 28, having recesses at one end for engaging one of theleg members from opposite sides and clamped thereon, as by clampscrew29, and with a pin 30 on one of the plates at the other end forextension through an aperture in the other plate. The pencil .or scriber31 is surrounded by a resilient clip 32, having ends projecting betweenthe plates 27 28 and engaged by the pin 30. By this arrangement it willbe obvious that the plates 27 28 may be adjusted to any desired point onthe leg member to which they are attached and the pencil or scriber 31likewise adjusted 5 to any desired degree and clamped firmly in positionby the single clamp-screw 29.

This makes a very convenient and efficient implement for all thepurposes for which similar implements are designed and may be .9inexpensively and strongly manufactured.

The implements-may be of any desired size and, of any suitable material.

Having thus described the invention, what isclaimed is 1. In animplement of the class described, leg members pivotally connectedintermediately of the same to a head member, a rod movable through saidhead member and connected by links respectively to the shorter I00 endsof said leg members and means operative in said head member foradjustably locking said rod in said head member.

2. In an implement of the class described, leg members reversely bent atone end and pointed at the other end, a head member pivoted to said legmembers at the bends in the same, a rod movable through said headmember, links movably connecting the bent ends of said leg members andsaid rod, and means for adjustably locking said rod to said head member.

3. In an implement of the class described, I leg members pivotallyconnected intermediately of the same to a head member, a rod movablethrough said head member and conthe presence of two witnesses.
